Dinghy Towing
If you have a front-wheel-drive vehicle, it can be
dinghy towed from the front. These vehicles
may also be towed by putting the front wheels on
a dolly. See "Dolly Towing" later in this section.
If you have an all-wheel-drive vehicle, it can
be dinghy towed from the front. You can also tow
these vehicles by placing them on a platform
trailer with all four wheels off of the ground.
These vehicles cannot be towed using a dolly.
For vehicles being dinghy towed, the vehicle
should be run at the beginning of each day and
at each RV fuel stop for about five minutes.
This will ensure proper lubrication of transmission
components. Put the IGN (Ignition) fuse in to
start the vehicle.

To tow your vehicle from the front with all four

1. Position the vehicle to tow and then secure it.
2. Turn the ignition to OFF.
3. Set the parking brake.
4. To prevent your battery from draining while
the vehicle is being towed, remove the IGN
(Ignition) fuse from the underhood fuse block.
See Underhood Fuse Block on page 493.
5. Turn the ignition to ACCESSORY.
